What is a Test Lab Sieve Shaker?
Lab sieve shakers are designed for efficient and reliable sieving of powders, granules, and other solid materials. They typically consist of a motor that drives a vibrating mechanism, which applies motion to the sieve stack. This vibration helps to stratify materials based on particle size, providing accurate and reproducible results.
Common features include adjustable vibration intensity, easy-to-use controls, and compatibility with different sieve sizes. Furthermore, it is compatible with ultrasonic mesh deblinding units, same as الغربال الاهتزازي بالموجات فوق الصوتيةs.They are used in various industries, including materials testing, pharmaceuticals, food science, and environmental analysis.
مبدأ العمل
An electromagnetic vibrator is used as the vibration source. The vibration from the vibrator drives the screen machine to vibrate at the base, which is then transmitted through the base to a set of standard test sieves arranged from coarse to fine. At the same time, a vibration motor (or reciprocating mechanism) installed at the bottom performs precise screening of the material. As the material vibrates on the surfaces of the standard test sieves, particles smaller than the mesh size fall through to the next lower sieve. This process continues layer by layer until each sieve retains particles of the same size, thereby achieving separation based on different particle sizes.

- ال lab sieve shaker features an exquisite exterior design, with a logical and secure arrangement of relay circuitry.
- The unit is lightweight and compact, making it convenient to position and relocate as needed.
- During the inspection process, it delivers high screening precision and efficiency, capable of sifting particles ranging from 0.025 mm to 3 mm.
- Enhanced through nanotechnological innovation, the test sieve is specially fitted with four high-elasticity rubber springs at its base, effectively and ingeniously eliminating any vibration of the unit while resting on a desktop or workbench.
- The machine operates with minimal noise during analytical screening, allowing for practical, real-world product verification.
- The sieve housing and vibrating plate of the 300T standard test sieve are meticulously crafted from high-quality SUS304 stainless steel.
- The screening duration is precisely controlled via a time relay, ensuring the inspection time is regulated with absolute accuracy—down to the very second.
- The sieve frame is made of SUS304 (0Cr18Ni9) stainless steel with a 0.6 mm wall thickness and a polished finish.The mesh is securely fixed by tin soldering, ensuring stability without loosening and heat resistance up to 300°C.
What is Test Lab Sieve Shaker Used For?
Ideal for labs, quality inspection departments and industrial production, sieve shaker machines serve pharmaceutical, metallurgy, abrasive, chemical and geological fields. They accurately analyze granular and powder samples to detect particle size distribution, liquid-solid proportions and impurity residues.
Capable of fast particle measurement between 125 mm and 20 μm, the unit supports ultra-fine custom sieves below 20 μm. Note that finer mesh screens tend to get clogged easily by certain solid particles. Specialized operating processes enable micro sieving as fine as 5 μm.
Type of Test Lab Sieve Shaker
The electromagnetic laboratory test sieve shaker utilizes an electromagnetic vibrator as its vibration source, employing high-frequency vertical vibration at rates of up to 3,000 cycles per minute. This action propels the material off the sieve mesh, preventing adhesion and enabling screening down to 20 microns (635 mesh)—thereby solving the challenge of dry screening ultrafine powders.
The standard tapping sieve shaker is a laboratory-grade screening device compliant with national standards. It employs a dual-action mechanism combining vibration and tapping, delivering high screening efficiency, precise particle size analysis, and excellent repeatability. It utilizes sieve frames with a diameter of 200 mm (a standard size) and supports a mesh range of 4 to 635 mesh. This equipment is widely used for particle size distribution testing across industries such as chemicals, metallurgy, pharmaceuticals, food processing, non-metallic minerals, and metal powders.
Compared to traditional test sieves, ultrasonic test sieves offer a 1%–70% improvement in screening precision and a 0.5–10-fold increase in throughput, with material passage rates rising by as much as 5–20 times; they enable the precise separation of fine particles with similar sizes and the control of narrow particle size distributions, achieving screening down to a minimum of 5–25 μm.

How to Choose the Right هزاز المنخل المخبري？
Lab sieve shakers are primarily available in three materials: woven wire mesh, perforated plate screens, and electroformed screens. These three materials have different mesh sizes, and the choice depends on the material being sieved. As long as you have a clear understanding of the particle size of the material and the characteristics of the sieve mesh, it is not difficult to select the test sieve that meets your needs.
Woven wire mesh
Materials include high-quality stainless steel, brass, tin bronze, nickel, and molybdenum. They are low-cost and highly durable, but offer relatively lower precision, and the mesh may deform. The precision of the mesh can be controlled by enlarging or reducing the mesh size. Generally, manufacturers capable of producing high-precision screens must ensure mass production and select screens that comply with the GB/T 6003.1-1997 standard from a large inventory of high-precision screens; these are most commonly used in the diamond industry.
Punched metal screens
These feature uniform punching precision and are resistant to deformation. They are primarily used for screening large particles and come in both round and square hole configurations. They are commonly used in round-hole slag powder collection screens and round-hole sand and gravel screens. Electroformed screens: Manufactured using electrochemical methods, these offer the highest precision, theoretically reaching 1 micron. However, due to variations in manufacturers’ processes and molds, there is significant variation in quality.
